N-[(2-Chlorophenyl)sulfonyl]-2-methoxybenzamide

Abstract

The title compound, C14H12ClNO4S, crystallizes with two molecules in the asymmetric unit. The dihedral angles between the benzene rings are 89.68 (1) (molecule 1) and 82.9 (1)° (molecule 2). In each molecule, intramolecular N—H...O hydrogen bonds between the amide H atom and the methoxy O atom generateS(6) loops. In the crystal, molecule 2 is linked into inversion dimers through pairs of C—H...O interactions, forming anR22(8) ring motif. Molecules 1 and 2 are further linked along theb-axis direction through C—H...π interactions. The crystal structure is further stabilized by several π–π stacking interactions [centroid–centroid separations = 3.7793 (1), 3.6697 (1) and 3.6958 (1) Å], thus generating a three-dimensional architecture.
